2 The Coleopterists Bulletin, 55(4): NEW SPECIES OF HEMIPHILEURUS KOLBE (COLEOPTERA: SCARABAEIDAE: DYNASTINAE) FROM MEXICO, GUATEMALA, COLOMBIA, AND BRAZIL BRETT C. RATCLIFFE Systematics Research Collections W436 Nebraska Hall University of Nebraska Lincoln, NE , U.S.A. Abstract The following new species of Hemiphileurus are described: H. bispinosus Ratcliffe from Brazil, H. deslislesi Ratcliffe from Colombia, H. quadridentatus Ratcliffe from Guatemala, and H. warneri Ratcliffe from Mexico. The parameres of H. rugulosus Endrödi (Venezuela and Colombia) are illustrated to enable easier identification of this species, and H. kahni Dupuis and Dechambre is redescribed and recorded from Brazil for the first time. Diagnostic illustrations of the male parameres are provided for the above taxa. A checklist for all the species in the genus is given. Resúmen Se describen las siguientes nuevas especies de Hemiphileurus: H. bispinosus Ratcliffe de Brasil, H. deslislesi Ratcliffe de Colombia, H. quadridentatus Ratcliffe de Guatemala, y H. warneri Ratcliffe de México. Se ilustraron los parámeros de H. rugulosus Endrödi (Venezuela y Colombia) para facilitar la identificación de esta especie. Hemiphileurus kahni Dupuis y Dechambre (Perú) es redescrita y registrada por primera vez en Brasil. Se proveen ilustraciones diagnóstico de los parámeros del macho para los taxa antes mencionados. Se incluye un listado de todas las especies del género. Where the telescope ends, the microscope begins. Which of the two has the grander view? Victor Hugo The genus Hemiphileurus contains the most species of any New World genus of Phileurini. Eighteen species are now found exclusively in South America, nine species occur in Mesoamerica (plus four additional in preparation by me), three species are found in both Central and South America, and 10 species inhabit the West Indies; one species is found in the Nearctic Region. Endrödi (1978, 1985) provided a synopsis of the genus, but additional species have been described since that time (Chalumeau 1988; Ratcliffe 1988; Ratcliffe and Ivie 1998; Dupuis and Dechambre 2000). As a result of recent collecting by several colleagues, four new species are described below as well as comments to aid identification for two other species. Species of Hemiphileurus seem to be collected only intermittently at lights or from logs, and so additional new species will continue to be found. Well over half of the species in the genus have been described as new during the past decade. 433

3 434 THE COLEOPTERISTS BULLETIN 55(4), 2001 Hemiphileurus kahni Dupuis and Dechambre (Figs. 1 3) Hemiphileurus kahni Dupuis and Dechambre 2000:26. This species was described from a single male specimen from Genaro Herrera, Loreto, Peru. The specimens listed below represent a NEW COUNTRY RECORD: BRAZIL: Amazonas; Rio Taruma Mirim Igapo; J. Adis, 2.IX.1976 (2 specimens) and 10.XI.1976 (1 specimen). Specimens are deposited at the Instituto Naçional de Pesquisas da Amazonia (Manaus, Brazil) and in the B. C. Ratcliffe collection. The Peruvian specimen was collected to the SSW of Iquitos where the El Capite river empties into the Ucayali which, in turn, almost immediately empties into the Amazon. The Brazilian specimens were taken near Manaus just above where the Rio Negro joins the Amazon. These two localites are approximately 1,540 km apart and are both characterized by lowland rainforest. The Brazil specimens represent a substantial range extension. Inasmuch as the description by Dupuis and Dechambre did not include a female, is based on only one specimen, and is overly brief, I provide below a detailed re-description. Male. Length 22.4 mm; width 10.7 mm. Color black. Head: Surface completely, transversely rugose. Frons with large, laterally compressed tubercle mesad of anterior border of each eye; surface between tubercles foveate, moderately rugose. Clypeus triangular, apex acute and strongly reflexed, a distinct carina extending from apex to base of each tubercle. Interocular width equals 4.5 transverse eye diameters. Antenna with 10 segments, club slightly longer than segments 2 7. Mandibles arcuate on lateral edge, apices acute. Pronotum: Surface finely shagreened, moderately punctate; punctures moderately large, each with a minute seta, punctures becoming slightly denser on sides. Median, longitudinal furrow shallow (nearly obsolete), becoming wider apically, not reaching base or apex. Base with complete marginal bead. Elytra: Surface with 5 distinct, punctate striae between suture and humeral umbone; punctures large, ocellate, separated from one another in each row by 1 2 puncture diameters. Intervals convex, with sparse micropunctures. Pygidium: Surface completely, densely punctate; punctures large, deep, setigerous; setae tawny in color, short, a few longer at center apex. In lateral view, surface strongly convex. Legs: Foretibia tridentate, teeth subequally separated. Median transverse carina on meso- and metatibiae ending in a long, acute spine on upper surface. Apex of posterior tibia with strong, acute spine on upper angle and with 8 short, broad spinules below spine. Apex of first tarsomere on posterior tarsus with strong, acute spine dorsally. Venter: Prosternal process broad, moderate in length, apex flattened into a concave, suboval plate (Fig. 3). Last sternite with small, dense punctures in lateral angles, elsewhere with small, sparse punctures. Parameres: Figures 1 2. Female. Length mm; width mm. As male except in the following respects: Pronotum: Punctures slightly larger. Elytra: Intervals slightly wider. Pygidium: Setae shorter. Venter: Last sternite completely, moderately densely punctate, punctures moderate in size. Remarks. Hemiphileurus kahni will key only to couplet 41 in Endrödi (1985) where the following two choices are for Mesoamerican species [H. laevicauda (Bates) and H. punctatostriatus (Bates)] that each have totally different parameres than H. kahni. The parameres (Figs. 1 2) of H. kahni are unique among species of Hemiphileurus and are diagnostic for the species. The distinct microsetae in the pronotal punctures are also unusual for a species of Hemiphileurus, but this may simply reflect a pristine specimen where the

5 436 THE COLEOPTERISTS BULLETIN 55(4), 2001 tiny setae have not been worn away; these setae are less noticeable in the two other specimens. The biology of this species is unknown. The specimens reported here were collected in arboreal photoeclectors mounted on tree trunks in an area of blackwater inundation forest (igapo) near where the Tarumã Mirim river empties into the Rio Negro about 20 km upstream from Manaus (Adis 1981). The photoeclector traps were modified to capture insects walking downward on the trunk of the trap tree. Hemiphileurus bispinosus Ratcliffe, new species (Figs. 4 5) Type Material. Holotype labeled BRAZIL: Minas Gerais, Belo Horizonte, UFMG, Estação Ecologica, IV-IV-1998, D. Yanega, ex blacklight. Holotype deposited at the Museu de Zoologia of the Universidade de São Paulo, São Paulo, Brazil. Holotype. Male. Length 16.0 mm; width 7.1 mm. Color black. Head: Frons in center with deep fovea, surface smooth; frons on sides with moderately-sized horns, horns erect and curving slightly posteriorly. Clypeus triangular, surface nearly smooth, with a few scattered, small, transverse punctures; apex acute and strongly reflexed, a weak carina extending from apex to base of each horn. Interocular width equals 4.0 transverse eye diameters. Antenna 10-segmented, club slightly longer than segments 2 7. Mandibles arcuate on lateral edge, apices acute. Pronotum: Surface weakly, finely shagreened, punctate; punctures in longitudinal furrow sparse, large, ocellate, punctures just either side of furrow sparse, small; punctures on disc moderate in density, large, ocellate, punctures becoming dense in anterior angles. Median longitudinal furrow deep, extending from base to anterior fifth of pronotum, furrow widest at middle. Base with complete marginal bead. Elytra: Surface with 5 punctate striae between suture and humeral umbone; punctures moderate to mostly large, umbilicate, separated from one another in each row by about 1 puncture diameter. Odd intervals slightly convex, becoming transversely wrinkled on sides of disc; even intervals with rows of punctures similar to those of striae. Pygidium: Surface moderately densely punctate; punctures moderate to moderately large, most setigerous either side of middle; setae short, tawny in color. In lateral view, surface regularly convex. Legs: Foretibia tridentate, teeth subequally separated. Median transverse carina on meso- and metatibiae crenulate. Apex of posterior tibia with strong, acute spine on upper angle and with several small serrations and a short, broad spinule between each serration (7 spinules on each side). Apex of first tarsomere of posterior tarsus extended into acute spine dorsally. Venter: Prosternal process short, subtriangular, flattened from front to back, and with small swelling on posterior face near base. Last sternite transversely rugopunctate to punctate in anterior half, apical half nearly smooth. Parameres: Figures 4 5. Etymology. From the Latin bi, meaning two, and spina, meaning spine or thorn; this combination of words in reference to the two distinctive, curved spines between the parameres of the male genitalia (Figs. 4 5), hence the twospined Hemiphileurus. Remarks. Hemiphileurus bispinosus will key to couplet 31 in Endrödi (1985) where neither of the subsequent two choices fit the character states. The parameres of H. bispinosus (Figs. 4 5) are remarkable because of the two, long, slender spine-like processes arising from between the parameres. Among all the other species of Hemiphileurus, only H. elongatus Dupuis and Dechambre from Bolivia has parameres with internal processes, but these are very different from those of H. bispinosus. In addition, the form of the prosternal process is unusually short and undeveloped in this new species relative to most other species in the genus.

6 THE COLEOPTERISTS BULLETIN 55(4), The biology of this species is unknown. The single specimen was taken at blacklights. Hemiphileurus deslislesi Ratcliffe, new species (Figs. 6 8) Type Material. Holotype labeled COLOMBIA, Calima Valley, 45 km. west of Buga. 29-III Holotype deposited at the Canadian Museum of Nature, Ottawa, Canada. Holotype. Male. Length 24.0 mm; width 11.4 mm. Color black. Head: Entire surface smooth. Frons with 2 large, arcuate horns, horns erect and curving posteriorly. Clypeus triangular, apex acute and strongly reflexed, a distinct carina extending from apex to base of each horn. Interocular width equals 5.0 transverse eye diameters. Antenna with 10 segments, club slightly longer than segments 2 7. Mandibles arcuate on lateral edges, apices acute. Pronotum: Surface finely shagreened, with punctures mostly large in size; punctures moderately dense in median furrow and on disc anteriorly either side of furrow, moderate in density elsewhere. Median, longitudinal furrow shallow, extending from in front of base to just behind apex, becoming gradually wider anteriorly. Apical tubercles absent. Base with complete marginal bead. Elytra: Surface with 5 distinct rows of punctate striae between suture and humeral umbone; punctures large, umbilicate, separated from one another in each row by about 1 puncture diameter. Intervals slightly convex, finely shagreened. Pygidium: Surface densely punctate (moreso than on elytral apices); punctures moderate to moderately large, less dense at apex, setigerous; setae minute, tawny in color. In lateral view, surface evenly convex. Legs: Foretibia tridentate, teeth subequally separated. Median transverse carina on meso- and metatibiae culminating with strong spine on upper surface. Apex of posterior tibia with strong, acute spine on upper angle and with several small serrations and a short, broad spinule between each serration (4 spinules on right side, 5 on left side). Apex of first tarsomere of posterior tarsus extended into long, acute spine dorsally. Venter: Prosternal process moderate in length with weakly expanded and suboval apex; shaft at middle on posterior face with obliquely transverse swelling and at base with strong, tooth-like swelling (Fig. 6). Last sternite densely punctate along anterior margin, moderately to sparsely punctate elsewhere. Parameres: Figures 7 8. Etymology. At the request of Martin Hardy, who generously provided me with the specimen, I take pleasure in naming this species after its collector, Gilles Deslisles, who has been a dedicated amateur lepidopterist in Quebec, Canada, for more than 30 years. Remarks. Hemiphileurus deslislesi will key only to couplet 36 in Endrödi (1985) where the following two choices are either H. cylindroides (Bates) or H. simplex Prell, both from Central America. The parameres of the males in each of these species are formed very differently from those of H. deslislesi. The parameres (Figs. 7 8) of H. deslislesi are similar to those of H. variolosus Burmeister (Fig. 9) as are the transverse carinae of the meso- and metatibiae. However, the prosternal process is tall, columnar, and with the apex broadly and triangularly flattened in H. variolosus (Fig. 10) whereas in H. deslislesi it is shorter, the shaft has transverse swellings, and the apex is not triangularly flattened (Fig. 6). In addition, the elytra in H. variolosus are strongly and densely punctate and lack the relatively smooth intervals of H. deslislesi. Nothing is known of the biology of this species. Like other species of Hemiphileurus, the larvae probably live in rotting wood, and the adults may not be strongly attracted to lights (personal observation).

7 438 THE COLEOPTERISTS BULLETIN 55(4), 2001 Hemiphileurus rugulosus Endrödi (Figs ) Hemiphileurus rugulosus Endrödi 1978:91. Endrödi described this species based on 43 specimens, most of which were from Venezuela; two specimens were from Colombia. Endrödi s (1985) key to the species of Hemiphileurus generally works for identifying this species, but when one attempts to confirm the identification by comparing the parameres of the specimen with the illustration in the book, considerable doubt sets in because the two don t appear to be the same. The reason for this is the oversimplified illustration which, unfortunately, is typical for so many of the drawings by Endrödi. When compared with specimens identified by Endrödi, the illustration is simply not accurate. To help alleviate this confusion, I am providing new illustrations (Figs ) of the male genitalia of H. rugulosus specimens collected at Rancho Grande (near Maracay), Venezuela as well as Endrödi s original drawing (Fig. 13). Hemiphileurus quadridentatus Ratcliffe, new species (Figs ) Type Material. Holotype labeled GUATEMALA: Izabal, SE Morales nr. Negro Norte, IV-1997, 1,000 m, N W, col. José Monzon.

9 440 THE COLEOPTERISTS BULLETIN 55(4), 2001 Etymology. This species is descriptively named for the four teeth present on the foretibia. Remarks. Hemiphileurus quadridentatus will key only to couplets 45/46, the last in Endrödi s (1985) key. Here one finds the only other continental species with quadridentate foretibiae: H. microps (Burmeister) and H. illatus (LeConte), both from Mesoamerica. A third continental species with quadridentate foretibiae, H. warneri, is described in this paper. The diagnostic male parameres must be examined for reliable identification because of overlapping external character states between the four species. The only other species with quadridentate foretibiae, out of 43 (currently) in the genus, are H. dispar (Kolbe) and H. parvus Dupuis and Dechambre, from Hispaniola and Cuba respectively. The specimens of H. quadridentatus were taken at lights along with several specimens of H. microps; nothing is known of their biology. Although the type locality near Negro Norte is only 1,000 m in elevation, it is a cloud forest because of the high amount of moisture received from the Caribbean ( 4,000 mm of rain/year). According to J. Monzon (pers. comm., September 2000), this forest is the northernmost limit for many Central and South American Cerambycidae as well as the metallic species of Central American Plusiotis (Scarabaeidae: Rutelinae) and other beetles. This is one of the most biologically rich forests in Guatemala and should be considered in any conservation programs there. Hemiphileurus warneri Ratcliffe, new species (Figs ) Type Material.

10 THE COLEOPTERISTS BULLETIN 55(4), (Chandler, AZ) who collected the specimen and provided it to me for description. Remarks. Hemiphileurus warneri is similar externally to H. illatus (Le- Conte) and will key to this species in Endrödi (1985). The parameres of H. warneri (Figs ) are different than those of H. illatus (Figs ). The most striking difference between the parameres, aside from the obvious length proportions, is the almost entirely concave surface of each paramere that abruptly becomes convex at the apices in H. warneri whereas in H. illatus there is only an oblong depression on the center of the paramere. In addition, the base of the last sternite in H. illatus is densely punctate to transversely rugulose in a narrow band while in H. warneri the entire surface of the last sternite is sparsely punctate and lacks any distinctive sculpturing across the base. The holotype was taken at a U.V. light trap in lowland deciduous forest in a mesic canyon at the end of dry season.
